EADIATOR FOR VEHICLES.

Specification of Letters Patent.

Patented July 25, 922.

Application filed April 10, 1919. Serial No. 288,906.

T 0 all 10 ii am it may concern Be it known that I, EDWARD R. Hnwrr'r, a citizen of the United States, residing 1n the town of Midvale, county of Passaic, State of New Jersey, have invented certain new and useful Improvements in Radiators for Vehicles, of which the following .1s a specification, reference being had to the accompanying drawings illustrative of one particular embodiment of my invention.

My invention relates to radiators such as are used on tractors or motor cars, or for other purposes. In particular it meets more advantageously the conditions of a slowmoving vehicle such as a farm tractor which cannot depend upon its speed for the circulation of cooling air about the radiator.

Tractors are slow moving, and furthermore are used in hot weather and a large volume of air' must therefore be passed through the radiating cells, in order to pro duce the proper results for satisfactory operation of the tractor.

I have developed a construction which meets the above requirements, and also provides a simple means for assembly and also for'inspection, cleaning or repair, and in all an economical construction, with parts readily replaceable and suitable for the :rough usage to which tractors are devoted.

An embodiment of my invention is shown in the accompanying drawings, in which- Fig. l is a front elevation of the radiator construction showing its mounting on a tractor frame. v

Fig, 2 is a part longitudinal section on the axis of the fan-shaft.

As shown in this form of construction, A--A are lateral radiator sections containing tubes a, with radiating fins and connected at the top with a dome B, havinga cap I; for filling. The junction between the dome and radiator sections A, is made by a fitting C which has a removable plate 13' bolted down and which may be removedto afford access to the upper ends of the radi ator tubes a. A. fitting C at the lower end serves to connect the lower portion of the radiator sections AA. with the water-circulating coupling E, and this junction C has a removable plateor cover D, to afiord access to the lower end of the radiator tubes. Thus the plates D and D. may be removed with the radiator and all connections in place, without disturbing them, except for the-removal of the water. This afi'ords a ready means of cleaning the interior of the radiator members.

The fittings CC afford means of connection by the cross-frame F holding the assemblage together and providing at its center a hub G for a bearing to support a fanshaft H. y

A fan J at one end and J at the other end, are driven by the same shaft with its pulley h, or any other suitable connection. The fans are oppositely pitched for the purpose ofdriving the air inwardly.

About the shaft H there is mounted a deflector K-K, comprising two oppositely disposed conical sections base to base, so proportioned as to laterally deflect the air entering at either end and drive the air through the radiating sections A-A.

Below the pipe connections E, theirintegral fittings or otherwise, serve as a base to support the entire structure on the channel bars L-L, which form the frame members of a tractor or other structure for which the radiator is particularly intended. The upper water connection to the radiator is shown at E, which leads to the proper engine water manifold to complete the circuit of the cooling water system.

It will thus be seen that the radiator structure may be mounted on the frame members of a tractor or other vehicle or platform, and irrespective of the outside air currents the fans at either end of the structure draw in a large volume of air and the cone surfaces deflect the air laterally about all of the radi ating surfaces, tank or other parts containing the cooling liquid. The radiator may be placed in front or behind the engine and all of the air driven by the fans is exhausted laterally, and therefore away from any of the other parts or the machinery of the us tor, avoiding unnecessary accumulation of dust and dirt.

In particular, the removal of the caps or plates D'-D, affords a means of access to the tubes of the radiator sections. They may be removed without displacing the frame and without displacing any other members of the assembled radiator structure, thereby Sim.- plifying the question of investigating and correction of any stoppage in thecirculatin system, as well. as periodic cleaning to avoi accumulation of scale and dirt.

' Various modifications may be made without departing from my invention, which may take the form of changing the fan oonnections or changing the form of deflectors from what is shown and specifically in the accompanying drawings. F or example a barrel fan or blower, some of which are now known as the Sirrooo type, taking the air in from one direction and discharging it at right angles, either from one or both directions will be found in some cases to serve the purposes of my invention, but

hat I claim and desire to secure by Letters Patent is:

1. In a power vehicle, an engine cooling apparatus comprising two radiating sections laterally disposed, a medial fan shaft and two oppositely pitched fans on said shaft, a stationary deflector intermediate said tans cooperating with said radiating sections whereby elther fan propels air to be deflected by the stationary deflector to the radiating section.

2. lln a power vehicle, a radiating system including two radiator sections one on either side of the vehicle and oppositely disposed, a fan shaft longitudinal of said vehicle and two oppositely pitched fans on said shaft one forwardly beyond the radiator sections and one rearwardly beyond the radiator sections and each turning in planes transverse to the vehicle, a stationary deflector intermediate said tans cooperating with the radiator sections to pass the air therethrough when projected against the deflector from either one of the two fans.

3. A radiator comprising two radiator sections symmetrically disposed on opposite sides ot a shatt, a shaft midway between said sections, two oppositely pitched fans operatively connected to said shaft and situated respectively in advance of and to the rear ct ti a radiator sections, a stationary shield ying between said radiator sec tions and between said tans having walls directing air propelled from the fans to impinge at ria tangles on said radiator secnon.

headers, and a spider frame at each bases, a bearing in each of said with diagonal arrns rigidly connecting headers end frames and a shaft in said bearing, tans surmounted on said shaft and a stationary masses shield rigidly held by said headers between the fans to deflect air propelled by the latter to impinge at right angles upon the radiator section.

in a power vehicle, a cooling system for internal combustion engines, a plurality of radiator sections in substantially parallel planes rigidly secured to said vehicle, fans mounted to rotate in planes transverse to the plane of the radiator sections, a deflector fixedly mounted with respect to said radiator section having walls deflecting said air current to impinge at right angles on the radiator sections.

6. In a power vehicle two radiator sections one on either side of the vehicle, acommon water tank detachably connected with the tops of said radiator sections, an

independent base for each of said sections,

a fan forward of the sections and a second fan to the rear of said sections oppositely pitched, a spider frame in front of and a. second spiderframe to the rear of said radiator sections having means rigidly securing said radiator sections together and supporting the fan bearings, and a stationary deflector intermediate said tans deflecting air to impinge at right angles upon the diator sections.

7. ln combination in a radiator structure for an internal combustion engine vehicle, two radiating sections laterally disposed, a medialtan shaft, two oppositely pitched fans on said shaft one in "front and the othor to the rear of the radiator sections, an intermediate stationary deflector, for the purpose described.

8.1K radiator structure for an engine, comprising two radiator sections oppositely disposed, a shaft midway between said sections, two fans oppositely pitched operatively connected to said shaft, a stationary shield between said tans contorming to proa current of air from the fans parallel .1

to the radiator sections to a right angle course to directly impinge upon said radiator sections.

in testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses, this 31st day of lvlarch, 1919.
